Do Tohatsu 4-stroke outboards come with crankcase oil already installed from the factory?
NO!!! Tohatsu 4-stroke outboards are not filled with oil from the factory. Before you start your 4-stroke outboard you must add oil to the crankcase. If you do not add oil, you will severely damage your outboard. Running a 4-stroke without crankcase oil would be like running your car without oil…the engine will seize up and you will end up having to replace the engine block/powerhead (this type of damage is not covered under warranty). Please consult your owner’s manual for the proper oil type and amount to add and for the proper break-in and operating procedures.
